' For mounting comparatively thin wheels and the hke the bearing points of said wheels are thickened or reinforced in such afmanner that stamped out flaps having holes form, after having been bent over, a nniltiple thickening of the simple bearing.

-' Bearings which are thickened in this manner require, owing to their greater friction su faqeya more frequent or stronger lubrication. In movements and similar driving gears this stronger and frequent lubricating is impossible owing to the insufficiency of said bearings, so that bearings 01. this type have not been practically used notwithstanding the advantage Which they offer tor these gears.

This inconvenience is avoided according to the invention by making the-flaps to be bent over more or less hollow according to the lubricating material used and by bend ing their concave side upon the wheel plate or the like. The hollow spaces which are thus formed serve for storing the oil so that the bearing points are permanently under oil and a steady and perfect working of the movement or. driving gear is ensured. It is no longer necessary to take to pieces the driving mechanism after a certain time for oiling the bearing points as theoil in the hollow' spaces is suflic ent for a permanent lubrlcating. The oil, owing to its surface tension, cannot escape from these morev or less great hollow spaces but nevertheless it is not necessary that the edges of the concave flaps bear tightlyupon the plate or the like as by the surface tension of the oil and the narrow interval between the plate and flaps a capillary efiect'is produced which retains the oil, in the hollow space until the last drop has" beenconsumed. It is' evident that the shape of the hollow flap to be bent over can bemodified according to prevailing conditions.

A form of construction of the bearing improved according to the invention on a plate for elect-ro-magnetic pocket-lamps is shown, by way of example, in the accompanying drawing, illustrating the different "forms of construction of a double or triple bearing.

In the arms of theT-shaped plate a (Fig.

In a similar manner, a bearingflap c is connected in I horizontal web'cl The two bearing fiapsc and 0 are of similar diameter as the parts I and. 6 As shown in Fig. 2 in section, these flaps c and c are pressed concave and it they are bent over.along the dot and dash lines of the webs (Z and (Z their concave sides rest upon the rounded parts Z) and b so that a hollow position with the parts 6 by a space is termed. Through the double bearing formed in this manner the bores e and e tor the journals are drilled. V l

Fig. 7 shows in front elevation and Fig. 8 in section on larger scale a bearing of this type, the flap f mounted on the plate f havingbeen bent over in the direction of the arrow (Fig. 8) so that a gapw exists between said plate f and the'edge of the flap f a hollowspace 9 being formed between the flap and the plate. Bores e are then made in the plate f and in flap f and the hollow space is filled with lubricating oil; This lubricating oil gets into the narrow gap beplate 71 at the sides of the part In, the flap Z 'llfl showing its concave side and the flap m showing its convex side.
